CLAIMS). FOR ANZESTHETIZING MACHINES;

Application filed March 11, 1927. Serial No. 174 471.'

My invention reiates to clamps for anaesthetizing machines. In the use of such ma-v chines now in common use, gas containers are held n gas supplying position by means oi yokel ke members extendlng out from the machine, the necks'ot' the containers being placed in these yoke members and screws carried thereby being turned down into engagement with the necks, This arrangement does not firmly secure the containers in place and they are capable of a swinging or rocking movement. An object, therefore of my invention is to provide a device by means of which the necks of the containers are firmly clamped and the containers prevented from having swinging or rocking movement, which movement causes leakage of gas around the customary gasket interposed between the neck of the container and the part containing the passageway leading to the interior of the machine. j

The full objects andadvantages of my invention will appear in connection with the detailed description thereof, and'the novel features of my inventive idea, will be par ticularly. pointed out in the claims;

In the accompanying drawingswhich illustrate two forms in may be embodied,'

Fig. -5 is a top plan view of this form with a small portion broken away. Fig. 6 is an end elevational view of the main portion of the clamp. Fig.

Referring firstto the form shown in Figs.

1,2, and 3, the numeral 10 designates a gas conducting member ofan anacsthetizing machine carrying the customary gas controllingdevice 12, gauge 14, and yoke member 16,;the latter supporting a customary gas container C. Containers of this character are com-j monly provided with a rectangular neck 18 having a discharge passage therein controlled by a needle valve 20. The clamp which con-' stitutes an important feature of the invention includes a plate 22 having a vertical notch 24 therein at its 'middle. Wedgewhich my invention Fig. 2 is a top plan.

dove-tail recesses in'the ends of the plate 22.,

Theouter surfaces or the wedge members extend at r1 ght angles to the plate 22 while their inner suriaces are inclined in such manner that they are closer to each other adjacent the plate 22 than they are asthey becomemore; remote therefrom. The outer portion of the, yoke member 16 is provided with a screwthreadedhole through which a screw 34 ex.- tends, The inner portion of this screw is provioed with a reduced stem 36 terminating in a conical head. 38 for engagement with the neck 18 of the container. A coiled spring 40 surrounds the stem In the use of the device the rectangular neck118 is properly posi: tioned in the yoke member 16 and the clamp is also placed therein so that the Wedge members26 and 28 engage opposite sides of the neck as shown in Fig.2 with the stem 36 ex-,

tending through the notch 24 and the spring shou der formed by the junction of the stem 1 with the main portion of the screw As th-elatt p turned in. the conicalhead 38 is brou 1 into engagement with the neck of the container, the spring40 is compressed and the edge members 26 and 28 are forced firmly into engagement with opposite sides of the .neckby the resilient action of the spring.

This serves to firmlyclampthe neck so that the c'ontainer is securely held. and prevented from swinging.

Inthe form shown' in Figs. 4 to 7', the clamp includes a plate 42 havinga vertical notch 44at its middle and a horizontal flange 46 at its upper end. VVedge-shaped members 48 and 50 are secured to the ends of thelplate- 42 and as shown are provided with dove-tail lugs 52 and 54 which fit into dove-tailrecesses in the ends of the plate. The outer surfaces of the wedge members extend at right angles to" the, plate 42 while their inner surfaces are inclined in such manner that they are closer to each other adjacent the plate than they are as they become more re mote therefrom.v The outer portion of the yoke member 16 is provided with a screwj into the notch 44. The inner end of: the reduced portion carries a head (32 which fits into a recess 64: around the notch n. The plate l2 when placed within the yoke 16 is retained therein for sliding movement by a small screw 66 which is turnen into the lower margin of the plate. In the use of this form of the device, the rectangular neck 18 is pl? seal in the yoke member 16 while the plate 42 is in retracted position. When the screw 56 is turned to advance the plate, the wedge members 48 and 50 are forced firmly into engagement with opposite sides of the neck so that the container is lirn'ily' held and prevented from swinging, and at the same time the neckot the cents her is forced against and compresses the customary gasket, thereby causing it to cal so that when the container is open to supply to the machine, the gas cannot escape into the his has the advantage that the mach e may be moved about without the container swin leakage of gas around the g I claim:
